Sky News reports on Trump's WEF Davos speech:

[https://news.sky.com/story/trump-latest-us-president-to-give-speech-in-davos-after-saying-world-will-find-out-how-far-hell-go-on-greenland-13489831#10893446]

Trump's explanation for why the existing defence treaty with Denmark (which allows the US to put as much military infrastructure as it likes in Greenland) isn't enough was startling and revealing. 

"All we're asking for is to get Greenland, including the right title and ownership, because you need the ownership to defend it. You can't defend it on a lease. Number one, legally, it's not defensible that way... And number two, psychologically, who the hell wants to defend a license agreement or a lease?"

So it is now crystal clear that President Trump regards Greenland like some tower block in Queens, where he used to collect rent for his father.

It's just a piece of real estate.

Like some rent-controlled NYC block where, once you acquire ownership, you can kick out all the existing tenants, do some gentrification and move in a lot of higher paying tenants or sell the apratments off as condominiums.
